After many rain delays, one of our farmers finally got the soybean population trial field planted on May 21^st.  The plots on this trial are 43’ wide and match the farmer's combine header width.  The only thing the farmer can do is display the as-planted data on the iPad and do a screen capture just to prove that the as-planted data matches and aligns with the prescription map.   In the past, you then used the harvest data along with the prescription file to analyze the data.

The farmer imported the screen captured .jpg image file into their SMS database and registered it so that the coordinates match the field boundary.  See the 3 images below.

We were curious to see if cover crop plots would be visible from the sky, so we went and took a look for ourselves. In the image below, you can see the difference in the cover crop field compared to the surrounding fields. 

You can really see the cover crops with NDVI (image below)

We were then curious to see how it aligned with the original design.  See below. It will be very interesting to compare the as-seeded data with this result. Maybe some plots were seeded but did not grow.

This remote sensing data might help predict the N credit from the cover crop.

On February 15, 2024, the UMN Precision Agriculture Center organized the 2024 On-farm Precision Agriculture Research Network Meeting to share and discuss the results of 2023 on-farm precision agriculture trials and plan for 2024 on-farm trials. The participants included collaborative growers, crop consultants, university researchers, graduate students, an USDA ARS scientist, Minnesota Department of Agriculture scientists and industry collaborators. In addition to the in-person meeting, an on-line option was also provided to those who could not join in person. 

Attached below you can find the notes, details, and pictures from the meeting. 

2024 On-farm Research Summary Meeting News

115 People participated in the Data-Intensive Farm Management Project's Conference that was held in sunny South Padre Island, Texas January 7-11th, 2024. We had 115 attendees from 12 countries who participated and listened to 50 presentations and 30 breakout/training sessions over the 4 days.  

The purpose of ICOFPE ’24 was to present and promote a revolution in agricultural sciences that moves agronomic experimentation from university- and corporate-owned fields to farmers’ own fields.  The conference brought farmers, crop consultants, and professional agricultural researchers together from all over the world who are interested in working with precision agricultural technology. Those professionals have interest in conducting meaningful agronomic field trials on farmers’ own fields, and then using the data generated to improve farm profits and enhance farm sustainability. 

The following is a breakdown of attendees:

Total registered: 115

We received some great feedback about the conference. Some attendees said:

-"There was a great balance between listening to technical and in the field experts and doing something through training and feedback."

-"The allocated time for each presentation struck an excellent balance, allowing for
comprehensive coverage without becoming overly lengthy or monotonous. The well-managed
timing not only facilitated a smooth flow but also ensured that the audience remained engaged
and attentive throughout the sessions. This approach greatly contributed to the overall
success of the event."

-"We really enjoyed the level of information that was put together for this meeting...The quality of speakers was top notch along with the information. If there will be another meeting next year we would like to be on the list."

During a trip to Colombia by Brendan Kuhns, it became clear that yield monitors for cotton are hard to come by, especially the kind that is retrofittable on older machines. Fortunately, DIFM researcher Dr. Tony Grift did his PhD on the development of a generic method for mass flow sensing of granular materials (fertilizers in particular), and he is eager to apply his method to cotton. We will build a new optical photo-interruption arrangement that measures the spacing durations between clumps of cotton passing a sensor. Then we will apply the theory of arrival processes to determine the number of cotton clumps that pass the sensor per unit of time, which is an indirect measure of the mass flow.

What is so fascinating about this method is that it works by only measuring the spacing times in between cotton clumps. So without knowing or measuring any material parameters, we still can measure the mass flow. It gets better: the measurement device does not need calibration, since nature is literally doing the work. If you would like to read details, here are links to paper 1 and paper 2 (the second won an award from the EurAgEng organization).

We hope that this small project will also connect our statisticians with the engineers (no easy feat!). For more information, feel free to read Dr. Grift’s essay titled “Embracing variability: How to hug a cactus”, which he claims to be “loosely based on the brother of our fearless leader David Bullock.”

Figure 1 Shown is the mass flow sensing scenario; we have clumps of material (cotton balls) and we measure the spacing durations among them. Believe it or not, using Poisson driven arrival theory, these data are sufficient to determine how many clumps are passing the sensor per unit of time, irrespective or the overlapping effect. Isn’t statistics great?

The USDA-funded Data-Intensive Farm Management (DIFM) Project is inviting farmers, crop consultants, and anyone else interested in digital agriculture to the 2024 International Conference for On-farm Precision Experimentation (ICOFPE ’24) being held on South Padre Island, TX during the second week of January.  The purpose of ICOFPE ’24 is to present and promote a revolution in agricultural sciences that moves agronomic experimentation from university- and corporate-owned fields to farmers’ own fields.  The conference will bring together from all over the world farmers, crop consultants, and professional agricultural researchers interested in working with precision agricultural technology to conduct meaningful agronomic field trials on farmers’ own fields, and then using the data generated to improve farm profits and enhance farm sustainability. 

DIFM is university-based and involves precision agriculture researchers and teachers from over twenty U.S. educational and research institutions.  The conference will provide farmers, crop consultants and others training in how to use DIFM’s “cyber-infrastructure,” which will allow users to design and conduct full-field agronomic trials, and then gain useful insights from the data generated on their own fields.  Use of the cyber-infrastructure is free of cost, and a large conference grant from the USDA’s National Institute for Food and Agriculture has made it possible to charge low conference registration fees.

We encourage you to visit our conference website at www.ofpe.org to register for the conference and learn more about the program and presenters. 

Jan. 8-9: Symposium I: “OFPE in Practice.”  For farmers, consultants, and anyone else interested in data-based crop production management.
